The Control lights up and can set time / Temp but it doesn't heat

Hello there and welcome to fixya there are several things that could make this dryer not heat up
Here are the most common things

Thermal Fuse

If the dryer doesn\'t heat, but the drum
turns, check the thermal fuse(s). The thermal fuse protects the dryer
from overheating and helps to prevent fires. If the thermal fuse is
blown, it will have to be replaced.

Gas Valve Solenoid

The gas valve has two or more electric
solenoids which open the valve to let the gas flow into the burner
assembly. If the dryer doesn\'t heat one or more of the solenoids may be
defective. If the igniter glows for 90 seconds but the burner flame
doesn\'t light, replace these coils as a set.


Dryer Igniter


If the dryer doesn\'t heat, the igniter might
be burned out. Check the igniter for continuity with an ohm meter. Dryer
igniters burn out over time, similar to a light bulb.

Heating Element

The heating element on an electric dryer can
burn out over time. If the dryer doesn\'t heat, the element should be
checked for continuity. The heating element cannot be repaired and must
be replaced if defective.

Heating Element Assembly

the heating element assembly on an electric
dryer can burn out over time. If the dryer doesn\'t heat, the element
assembly should be checked for continuity. The heating element assembly
cannot be repaired and must be replaced if defective.

Flame Sensor



Gas dryers have a flame sensor to detect the
heat given off by the flame. If the dryer doesn\'t heat, the flame sensor
might be defective. Check the flame sensor for continuity. This is not
as common as a burned out igniter or thermal fuse.


High Limit Thermostat


Although not common, if the dryer doesn\'t
heat the high limit thermostat can be defective. It can be checked for
continuity. If the thermostat is "open" the dryer doesn\'t heat.


Cycling Thermostat




The cycling thermostat regulates the
temperature of the air in the dryer. If the dryer doesn\'t heat it may be
caused by a defective cycling thermostat. This is not common.


Main Control Board

The main control board is normally not at
fault when the dryer doesn\'t heat. Check all of the other components in
this troubleshooting guide before replacing the main control board. The
main control board cannot be tested easily and must be replaced if it is
defective.


Timer
The timer is normally not at fault if the
dryer doesn\'t heat. In many situations where timers are replaced they
end up being returned. Check all of the more common components in this
troubleshooting guide before replacing the timer

You have a problem most likely with the air temerature control blend door actyautor or the door is jammed or in most cases both. Repair requires the dash to be removed so have it properly diagnosed as the repair is well over $1000.00

It sounds like the fan control AFC not cutting in on temp rise . But working in summer mode .

see this causes and fix it. God bless you
Thermal Fuse If the dishwasher won't start the thermal fuse might have blown. The thermal fuse helps to prevent damage to the dishwasher by turning off power so that it doesn't overheat. Once blown, the thermal fuse will have to be replaced for the dishwasher to work.

Door Switch The door switch, or switches, are sometimes called interlock switches. The door switch prevents the dishwasher from running while the door is open. If the dishwasher won't start, the switch or switches might be defective. To access the door switches, remove the control panel or inside door panel - depending on the model. They can be tested for continuity.

Main Control Board The main control board provides power to nearly every component of the dishwasher. If the dishwasher won't start the main control board might be defective. YOU should first check for more common parts. Many times control boards are replaced unnecessarily because the problem was not diagnosed properly.

Touchpad and Control Panel If the touchpad is defective, the control board might not get the signal for the selections made. If the dishwasher won't start and the display doesn't seem to change properly when the buttons are pressed, the touchpad might need to be replaced. On some models the touchpad and control panel are sold together and will need to be replaced at the same time.

Timer The timer allows power to flow to the proper parts at the proper times. If the dishwasher won't start, the timer might be defective. Keep in mind that timers are often misdiagnosed as the cause of a problem. Check other components first before replacing the timer.

The control board is bad. One of the relays has fused and you will need to replace the control board.

Hi

This means a loose/broken wire on the oven temp sensor or the oven temp. sensor itself is bad and should be replaced. To solve this issue test the oven temp. sensor, it should read between 1080-1120 ohms, if the rating is more then that and the door appears to be closing fine then it is the control board that is bad and should be replaced. Hope this helps...please post back for further assistance.

II might need the actual model number. However, you can go to page 9 on this manual and check if the flashing options can fix the problem. I am assuming you have already tried to turn the power off and back on.

The ohter thing to try is the reset sequence. Within 6-7 secs press High Temp/ Heat Dry/ High Temp/ Heat Dry/ High Temp/ Heat Dry. All lights should light up, press Start button to exit.

Hi,
The very best way to get parts will be to contact Masterbuilt directly..
